[PATCH] ASoC: blackfin: constify snd_pcm_ops structures

From: Arvind Yadav
Date: Mon Aug 14 2017 - 01:56:25 EST


snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/soc.h> work with
const snd_pcm_ops. So mark the non-const structs as const.
